براغي رأس سداسي M20-2.5 X 160mm | فئة 10.9 فولاذ عادي | خيط جزئي (10/عبوة)

The head is machined cleanly enough that my 32mm socket slid on without any wobble, and the partial threads grabbed firmly in the blind hole I was working with. Nice to have a solid ten pack for the price of a single specialty bolt at the local hardware store.

The hex head on these grabbed my socket perfectly without any slipping, and the 10.9 steel feels rock solid for the heavy flange alignment I used them on. Threading them into blind holes was smooth, too.

The partial threading on these M20 bolts is exactly what I needed for a machinery base plate where full threads would have interfered. The hex head gripped securely with a socket, and the class 10.9 steel feels solid enough for heavy assembly work.
